Problems solved by technology

The mechanism of organic ultraviolet absorbers is to capture or quench the active free radicals generated by high-energy ultraviolet rays breaking polymer molecular chains, but organic ultraviolet absorbers are all small molecular weight organic compounds, whether it is the absorption of ultraviolet light or the The capture of free radicals has certain limitations, and with the prolongation of use time, migration and degradation will occur, resulting in the gradual decline in the anti-ultraviolet light performance of the material and eventually failure
However, ultraviolet shielding agents such as ZnO have problems such as high photocatalytic activity and insufficient absorption capacity on the short wavelength side of ZnO.
[0005] In addition, there is also the prior art of applying nanoparticles with anti-ultraviolet function to nylon fibers, but such nanoparticles are small and have a large specific surface area, and are prone to agglomeration in nylon fibers
The general way to solve the agglomeration is to add conventional surfactants. The principle of these surfactants to solve the agglomeration is to eliminate the surface charge of the nanoparticles and enhance the lipophilicity of the nanoparticles, so that the nanoparticles can be doped into the nylon fiber. However, the stability of this method of combining nanoparticles with nylon fibers is still not good enough, which greatly reduces the anti-ultraviolet performance of the nylon fibers; to the color of the material itself

Abstract

The invention relates to the technical field of polyamide fiber materials, and particularly discloses an anti-ultraviolet polyamide fiber and a preparation method thereof. The preparation method comprises the steps that firstly, triisopropyl borate, 2-amino-3-hydracrylic acid and dihydric alcohol serve as raw materials to prepare a double-functional-group chelating type borate coupling agent with amino and carboxyl; the nano rare earth oxide is modified by adopting the synthesized coupling agent, in-situ polymerization is carried out on the modified nano rare earth oxide and caprolactam to prepare nylon resin containing the nano rare earth oxide, and finally spinning is conducted to prepare the polyamide fiber. The polyamide fiber obtained by the invention has more lasting, more stable and excellent anti-ultraviolet performance.

Description

technical field [0001] The invention belongs to the technical field of nylon fiber materials, and in particular relates to a nylon fiber with anti-ultraviolet performance and a preparation method thereof. Background technique [0002] Since the 20th century, with the acceleration of modern industrial processes, exhaust gas emissions and the use of various fluorides, the ozone layer has been damaged to a certain extent, and the ultraviolet radiation reaching the ground has gradually increased, resulting in increasingly serious harm. In the face of increasingly serious environmental problems, people pay more attention to their own protection in addition to the protection of the environment. Anti-ultraviolet textiles, like other protective products, have received people's attention. At present, the research and development of anti-ultraviolet functional fabrics is being carried out internationally, and anti-ultraviolet finishing has become a new and very promising development d...
